Most of the time just use some aspect of a flyer or template that I like. I’ve probably used maybe 30% of the templates I’ve actually purchased. Some I haven’t even downloaded yet. Like having new clothes with tags still on them.. lol

I would suggest you modify the center image with one that has more of the same realness as the border. And the leaves at the top seem to be a vector, perhaps look for a nice HD image and add some vines running down, to embellish the sides.
